UNITED STATES PATENT OFFICE. MARION E. MCMASTER, OF MONROE (JIIY, MISSOURI. PROCESS OF TREATING PAINT.

Be it known that I, MARION E. MOMASTER, a citizen of the United States, residing at Monroe City, county of Monroe, and State of Missouri, have invented a new and useful Process of Treating Paint, of which the following isa specification.

This invention relates to a process of treating paint. I .The object of the invention istorender paint more durable, elastic, and insoluble and one that will not chalk, crack, or peel off when once properly applied to any surface, such as wood, brick, iron, stone, or plaster.

With the above and other obj ects in view,

- as will appear as the nature of the invention is better understood, the same consists, gen

erally stated, in first rendering milk antiseptic by incorporating therewith mercuric chlorid and then incorporating the antisepticized product with paint.

In carrying the invention into effect sweet milk, either whole or that from which the butter-fat has been separated, is taken, and to it is add-ed in solution an antiseptic agent, preferably mercuric chlorid, and after the antiselptic has been thoroughly incorporated wit the milk it is stirred into and thoroughly combined with the aint. In preparing the milk the mercuric c orid is first dissolved in hot water, and this is added to the milk, the proportion being about from five to ei ht grams of the antiseptic to one gallon of k.

The antiseptic operates to keep the milk sweet and renders the casein insoluble.

In use the treated milk is added to any Specification of Letters Patent. Application filed Novernber 16, 1904. $erial No. 232.985.

Patented Nov. 28, 1905.

to be paintedand is thoroughly incorporated therewith by stirring. For general house.- work it has been found that one gallon of the milk to-one gallon of paint gives excellent re,- sults. To combine the milk with the paint, the former is slightly warmed and is added gradually to the paint, the latter being stirred until all of the milk is thoroughly incor orated with it and after which it can be use as any ordinary paint. If the product be too thick,

good ready-mixed paint in any quantity or proportion that may be desired for the work it may be thinned with linseed-oil. To give the painta flat surface a small quantity of paraflin oil may be added thereto after th milk has been incorporated.

Having thus described the invention,what is claimed is 1. The herein-described method of treating paint, which consists in incor orating' therewith milk to which has been ad ed mercuric chlorid in solution.

2. The herein-described method of treatinnfi paint which consists in adding to sweet k, mercuric chlorid in solution, thoroughly incorporating the antiseptic with the milk, then heating the milk, and stirring it into the paint.

In testimony whereof I have hereunto affixed my signature in the presence of two subscribing witnesses.
